@alanajjar you can describe what you found on Arabic Wikipedia related to the page freezing and not showing block message when adding a category with a gadget. I would appreciate you sharing the particular details and screenshots.

Thanks @SPoore

First
Gadget-hdedit.js

• I blocked Alaa account from editing the page نظير إنزيمي with an expiration time of 1 day (autoblock disabled).
• I try to edit same article then I can't edit it as expected. (Block ID #236075)
• When I try to use (Gadget-hdedit.js) it's not give me any block message or access denied message, only the section header freezes instead (like in photo below).

Second
Gadget-Cat-a-lot.js

• I blocked Alaa account from editing the page نظير إنزيمي with an expiration time of 1 day (autoblock disabled).
• I try to edit same article then I can't edit it as expected. (Block ID #236075)
• When I try to use (Gadget-Cat-a-lot.js) it's not give me any block message or access denied message, instead it give me (done) but without any action (like in photo below).

Third
Gadget-rater.js

• I blocked Alaa account from editing the talk page نقاش:نظير إنزيمي with an expiration time of 1 day (autoblock disabled).
• I try to edit same article then I can't edit it as expected. (Block ID #236075)
• When I try to use (Gadget-rater.js) it's not give me any block message or access denied message, instead it give me (done) but without any action (like in photo below).

Other gadgets working well (like Gadget-HotCat.js) be giving me the block message.

I've had a look into these issues:

Gadget-hdedit.js

I tested this with partial blocks disabled - it was broken before partial blocks was enabled. The problem is that it is checking for a property on an object that may not exist.

It can be fixed by replacing the line:

if (data.edit.result == 'Success') {

with:

if (data.edit && data.edit.result == 'Success') {

After doing that, a blocked user sees an appropriate block message.

Gadget-Cat-a-lot.js

I get errors when I try to use this gadget, even when I am not blocked - although they are different from the errors reported. That makes me suspect that it may have been broken before partial blocks was enabled.

Gadget-rater.js

I'm struggling to find any instructions on how to use this gadget, so haven't been able to replicate the problem. @alanajjar Would you mind testing it for an unblocked user and a sitewide blocked user, to check whether it is an issue with partial blocks?

Sorry for late in reply, I didn't notice it!!

Fixed. Confirmed (photo below)

Per Gadgets-definition

Cat-a-lot[ResourceLoader|rights=review|dependencies=mediawiki.util]|Cat-a-lot.js|Cat-a-lot.css

So you should have editor flag to try it. Please give me your SUL name and I'll grant you this flag.

Same thing need editor flag. I tried it with sitewide blocked user, and it appear not related to partial block only.
